The PSA Series 5 is sufficiently small and lightweight to fit comfortably into the hand - unlike most other so-called handheld spectrum analyzers. A removable screen protector and sun-shield combines with rubberised buffers top and bottom to enhance its use in the field.

The PSA Series 5 operates from a Li-ion rechargeable battery that can provide more than three hours of continuous operation. If switched off to conserve power, it returns to normal operation within a few seconds of switch-on with all data retained. It can also be set to switch off automatically after a set time from the last action. For continuous bench top operation it can be powered from its AC adaptor which also recharges the batteries in less than 3 hours.

With nearly 2GB of internal memory, the PSA Series 5 can store thousands of waveforms, instrument set-ups, or complete screen images. With option U02 installed, it can also log tens of thousands of results and make use of compensation tables and limit patterns. All files can be saved with either default file names or with user defined
names using the alpha-numeric keypad. USB Flash drives can be used to copy and backup data, or transfer it to a PC for analysis. Alternatively a USB device interface is
included for direct connection to a PC for file transfer.

The casing of the PSA Series 5 includes rubberised buffers top and bottom to help resist knocks and scratches. The tilt stand can be moved to the top of the instrument to act as a screen protector when in transit. In this mode it can also act as a sun-shield when in the field.

The small size fits perfectly into the hand and the low weight of only 560 grms (20 oz) allows it to be carried anywhere.
